Title:
METHOD FOR IMPROVING A CHEMICAL PRODUCTION PROCESS
Document Type and Number:
WIPO Patent Application WO/2019/138118
Kind Code:
A1
Abstract:
The invention relates to a method for improving a chemical production process, wherein a plurality of derivative chemical products (1a, b) are produced through a derivative chemical production process based on at least some derivative process parameters (3a, b) at a respective chemical production facility (2a, b), which chemical production facilities (2a, b) each comprises a separate respective facility intranet (4a, b), wherein at least some respective derivative process parameters (3a, b) are measured from the derivative chemical production process by a respective production sensor computer system (5a, b) within each facility intranet (4a, b), wherein a process model (6) for simulating the derivative chemical production process is recorded in a process model management computer system (7) outside the facility intranets (4a, b). The method is characterized in that, that the process model (6) is transmitted to respective computing modules (8a, b) for performing numerical analysis within each facility intranet (4a, b) from the process model management computer system (7), that the derivative process parameters (3a, b) at each chemical production facility (2a, b) are provided to the respective computing module (8a, b) and that each computing module (8a, b) determines respective modification data (9a, b) for updating the process model (6) by a numerical analysis based on the derivative process parameters (3a, b) at the respective chemical production facility (2a, b) and the process model (6). The invention also relates to a corresponding system for a chemical production process.
